A power supply device 13 for supplying a driving voltage to the chassis 11 is mounted, and a control circuit 14 for controlling display of each LED display module 12 is attached to the chassis 11.

As shown in the figure, the LED display module 12 includes a plurality of LEDs mounted on a substrate 12a in a dot matrix form, and is controlled by a control circuit 14 so that a driving voltage from a power supply unit 13 causes a change in voltage. Predetermined L
The ED is turned on so that a desired display pattern can be turned on and displayed.

The LED of each LED display module 12 is
Wirings are appropriately connected to the power supply device 13 and the control circuit 14 mounted on the chassis 11, respectively. Further, the power supply device 13 includes a connection terminal 13a to which a power supply voltage is input from the outside, and the control circuit 14 further includes a control input terminal 14a to which a control signal regarding display from a display input device (not shown) is input. Is equipped with. Thus
The LED display unit 10 has a power supply device 13 and a control circuit 14 which are independent of each other.

The embodiment of the present invention is constructed as described above. When a large LED display device is constructed by using a plurality of LED display units 10, it is assembled as shown in FIGS. 3 and 4. To be That is, the large-sized LED display device 20 is composed of a total of nine LED display units 10 by arranging three LED display units 10 in each of the horizontal direction and the vertical direction.

Each of the LED display units 10 is incorporated in a case 21, and the connection terminals 13a of the power supply device 13 are respectively connected to the power supply terminals 22 attached to the back surface of the case 21, as shown in FIG. The control input terminals 14a are connected to the control terminals 23 attached to the back surface of the case 21, respectively. Thus, each LED display unit 10 is easily incorporated into the large LED display device 20.

Here, when a failure or the like occurs in any of the LED display modules 12 of the LED display units 10 constituting the large-sized LED display device 20, the LE is displayed.
Only the D display unit 10 is removed from the case 21,
It will be replaced with a new LED display unit 10.

In this case, the LED display unit 30 has a connection terminal 13a of the power supply device 13 on its end surface, preferably side surface and upper surface and lower surface. And a connection terminal portion 31 connected to the control input terminal 14a of the control circuit 14.

The connection terminal portion 31 is arranged at the end face of the LED display unit 30 so as not to project from the surface.

Here, the connection terminal portions 31 are all female terminals, and when the LED display units 30 are assembled, the connection terminal portions 3 of the adjacent LED display units 30 are connected.
By inserting the male connection pins 32 at both ends between the connection terminals 1 and 1, the corresponding connection terminal portions 31 can be connected to each other.

In the connection terminal portion 31, only the connection terminal portion provided on the right side surface or the left side surface and the upper surface or the lower surface of the LED display unit 30 is a female terminal, and the connection terminal portion on the other side is a male terminal. Even in the case of mold terminals, the corresponding connection terminal portions 31 can be connected to each other when assembled in the same manner.

Further, the connection terminal portion 31 may be a contact type terminal. In this case, when the LED display units 30 are assembled adjacent to each other, the corresponding connection terminal portions 31 come into contact with each other so that they can be electrically connected.

The LED display unit 30 having such a configuration
According to this, at the time of assembly, the connection terminal portion 31 of each LED display unit 30 can be easily connected to the connection terminal portion 31 of the adjacent LED display unit 30.
Therefore, when the large-sized LED display device 20 is configured, the assembling work can be performed more easily and in a shorter time.
